| 英文摘要: |
| This paper is aimed at analyzing and evaluating the measurement accuracy of infrared radiation imaging characteristics of ground targets in a complex background environment based on the principle of infrared radiation imaging measurement and calibration. In this paper, eight error factors in dynamic infrared radiation imaging measurement of ground target in complex environment are analyzed, which result from equipment performance, environmental interference, operation parameter setting and relative motion. The error factors of ground target dynamic infrared radiation imaging measurement in complex environment are analyzed. The calibration blackbody and the measured target are simultaneously calibrated at the same distance and field of view. The measurement uncertainty factors are evaluated based on the test method, and the uncertainty evaluation model of infrared radiation apparent temperature measurement for ground equipment is established. Through the analysis, under the condition of 95% confidence probability, the measurement uncertainty of static and dynamic infrared radiation apparent temperature of typical ground vehicle target is 1.60 ℃ and 2.64 ℃ respectively. The characterization and evaluation method of infrared radiation imaging accuracy of ground vehicle target in a complex background environment based on infrared thermal imager is formed. It has an reference significance for accurate measurement of infrared radiation characteristics of ground equipment and accurate evaluation of infrared camouflage performance. |
